Nice job on the PAT, but the RC, Bio and Science GPA are really gonna bite you when the admissions people review the applications... hope you have some outstanding EC's, LOR's, PS, etc. Assuming you just applied, I don't think your chances are too hot for this cycle since it's a little late. I wish you the best of luck in securing an interview. As a contingency plan, start looking into doing some post-bac upper level sciences, as well as see how you can improve your DAT score (which you should definately retake)
All the best.
